5XZ-5 Gravity separator is according to segregation phenomenon of granule and density under fluidization process, for achieve materials delaminating and mutual exchange, at the same time the wind pressure and amplitude need be adjusted. Specific gravity separator is used to classify materials according to density or specific gravity. This is important when seed and/or impurities are similar in size but different in density. The separator uses a vibrating perforated deck that can be tilted in two directions at various pitches. Air moving through the perforated deck separates the seed and any impurities by weight as the deck oscillates.
